Ok now that I finally understand how hybrid fueling works I think it is high time I start on building one. The part I am still little fuzzy about is building these things strong enough to withstand the shock wave upon ignition anyhow I got a idea in my head and I would like to get a seal of approval from you guys BEFORE I start. like I said I am still in the design phase anyhow here is my idea for a chamber it is going to be composed from a thin shell of steel with a thick inside of A356 aluminum...

ughh I am crap at explaining anything, on to a diagram

the wall thickness of the aluminum is going to be 20mm thick I added the fiscal properties of A356 aluminum at the bottom

my question in short is: will this be strong enough for a 10X hybrid

and like most of us, I have already tried my hand at modeling this cannon in HGDT I am hoping it turns out close to this
